New Delhi, July 30 (TIWN) Jails no more bar the underworld dons and gangsters from carrying out their nefarious activities, including extortions.

A number of cases have come to light recently which revealed how the gang lords, lodged in Tihar and some other jails in the National Capital Region (NCR), carried out their operations through WhatsApp calls using wifi or VOIP (voice over internet protocol) numbers. The WhatsApp calls are meant to dodge the jammers in place.
